Quantum chromodynamics (QCD) is widely accepted as a fundamental theory to study strong interaction. However, for hadron-hadron interactions and exotic quark states, it is difficult to use QCD directly to study low-energy hadronic interaction because of the nonperturbative complication. Therefore, it has triggered kinds of QCD-inspired models, which study the muliquark systems from the physical perspective. The quark delocalization color screening model (QDCSM) is one of the representations of the constituent quark models, which was developed in the 1990s, aiming to explain the similarities between nuclear and molecular force [1]}. The model modifies the Hamiltonian by introducing the shielding effect of color screen and expands Hilbert space by considering the quark delocalization between two quark clusters. This model has been well applied to describe the properties of the deuteron [2]}, study the \(NN\)  and \(YN\)  interactions, and investigate the dibaryon candidates [3]}, [4]}, [5]}, [6]}. It has also been extended to observe the dibaryon states with heavy quarks, such as the \(N\Lambda _{c}\)  and \(N\Lambda _{b}\)  systems [7]}, and the possible \(H-\) like dibaryon states \(\Lambda _{c}\Lambda _{c}\)  and \(\Lambda _{b}\Lambda _{b}\)  [8]}, the \(N\Omega \) -like dibaryons \(N\Omega _{ccc}\)  and \(N\Omega _{bbb}\)  [9]}, the fully heavy dibaryons [10]}, and so on. It is interesting to search for more dibaryons in heavy quark sector within the frame of QDCSM.
